   We introduced a deterministic formatter in apache/logging-parent#59.
   
   The process of choosing the right formatter started on September 20th in 
[this `dev` 
thread](https://lists.apache.org/thread/t2fxkk4cx6x70wx8m1ld0n75nq39j62f). The 
choice fell on 
[palantir-java-format](https://github.com/palantir/palantir-java-format), 
because:
   
   - it has an excellent Java 8 (lambdas) support (compared to 
[google-java-format](https://github.com/google/google-java-format)),
   - it is largely compatible with our [previous Java Style 
Guide](https://logging.apache.org/log4j/2.x/javastyle.html). Compared to the 
Google Java Format, it uses an indentation of **4** spaces instead of **2** 
spaces,
   - compared to the [Eclipse Java 
formatter](https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fpreferences%2Fjava%2Fcodestyle%2Fref-preferences-formatter.htm)
 it has no formatting options. This is actually an advantage, since it prevents 
discussing each one of the hundreds Eclipse options. Moreover some Eclipse 
options render the formatting non-deterministic,
   - it provides support for both our build environment (Spotless) and IntelliJ 
IDEA editor,
   
   In order to provide support for the Eclipse IDE, we ported Google's Java 
Format Eclipse plugin to `palantir-java-format`: 
palantir/palantir-java-format#949.
